Rthe driver's door is open and the driver's
seat belt is unfastened.
Rthe engine is switched off.
Ra system malfunction occurs.
Rthe power supply is not sufficient.
On steep uphill or downhill inclines or if there

AIRMATIC package
General notes
AIRMATIC regulates the level of your vehicle.
As well as level control (Ypage 218), your
vehicle can be equipped with ADS (Adaptive
Damping System) (Ypage 217) and ACTIVE
CURVE SYSTEM (Ypage 218).
Observe the notes on driving with a trailer
(Ypage 264).
ADS (Adaptive Damping System)
General notes
ADS adapts the damping characteristics to
the current operating and driving situation.
This depends on:
Ryour driving style
Rthe road surface conditions
Rthe ADS setting
Rthe vehicle level setting
Your selection remains stored even if you
remove the SmartKey from the ignition lock.
Sports tuning
Example: vehicles without the ON&OFFROADpackage
CSuspension tuning button
DIndicator lamp for sports tuning

The vehicle automatically adjusts to highway
level when you:
Rdrive faster than 50 mph (80 km/h).
Rdrive between 40 mph (64 km/h) and
50 mph (80 km/h) for approximately
20 seconds.
Depending on the ADS mode selected
(Ypage 217), the vehicle is lowered to high-
speed level at high speeds.

Important safety notes
GWARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is a risk of
injury.
Make sure no one is underneath the vehicle
or in the immediate vicinity of the wheel
arches when the vehicle is being lowered.
GWARNING
The vehicle is lowered if:
Ryou have selected the Comfort or Sport
suspension tuning and
Rlock the vehicle after switching off the
engine
Persons in the vicinity of the wheel arch or the
underbody may thus become trapped. There
is a risk of injury.
Make sure that nobody is in the vicinity of the
wheel arch or the underbody when you switch
off the engine.
!The vehicle is lowered by approximately
10 mm if:
Ryou have selected the Sport or Comfort
suspension tuning and
Ryou switch off the engine and then
Rlock the vehicle
When parking, position your vehicle so that
it does not make contact with the curb as
the vehicle is lowered. Your vehicle could
otherwise be damaged.
Vehicle level
Level control adapts the vehicle level
automatically to the current operating and
driving situation. Level control ensures the
best possible suspension and constant
ground clearance, even with a laden vehicle.
This improves driving safety and fuel
consumption.
The AIRMATIC package and ACTIVE CURVE
SYSTEM are always components of AMG
adaptive suspension system (Ypage 217).
Due to the sportier suspension settings
compared to standard vehicles, the levels and
speed thresholds for sinking and raising the
vehicle are different.
In Comfort and Sport driving modes, after
locking the vehicle it lowers to the Sport+
level. When locking the vehicle at the raised
level, the vehicle does not lower.
The settings will remain stored after you
switch off the engine. When starting the
engine, the selected setting, e.g. AMG
adaptive suspension system Comfort, is
restored.
iThe vehicle level may change visibly if you
park the vehicle and the outside
temperature changes. If the temperature
drops, the vehicle level lowers; with an
increase in temperature, the vehicle level
rises.
Suspension tuning
General notes
The electronically controlled damping system
works continuously. This improves driving
safety and ride comfort.

Important safety notes
GWARNING
If wheels and tires of the wrong size are used,
the wheel brakes or suspension components
may be damaged. There is a risk of an
accident.
Always replace wheels and tires with those
that fulfill the specifications of the original
part.
When replacing wheels, make sure to use the
correct:
Rdesignation
Rmodel
When replacing tires, make sure to use the
correct:
Rdesignation
Rmanufacturer
Rmodel
GWARNING
A flat tire severely impairs the driving,
steering and braking characteristics of the
vehicle. There is a risk of accident.
Tires without run-flat characteristics:
Rdo not drive with a flat tire.
Rimmediately replace the flat tire with your
emergency spare wheel or spare wheel, or
consult a qualified specialist workshop.
Tires with run-flat characteristics:
Rpay attention to the information and
warning notices on MOExtended tires (tires
with run-flat characteristics).
Accessories that are not approved for your
vehicle by Mercedes-Benz or that are not
being used correctly can impair operating
safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist
workshop and inquire about:
Rsuitability
Rlegal stipulations
Rfactory recommendations
Information on the dimensions and types of
wheels and tires for your vehicle can be found
in the "Wheel/tire combinations" section
(Ypage 432).
Information on air pressure for the tires on
your vehicle can be found:

Operation
Information on driving
If the vehicle is heavily loaded, check the tire
pressures and correct them if necessary.
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicate that
the wheels or tires are damaged. If you
suspect that a tire is defective, reduce your
speed immediately. Stop the vehicle as soon
as possible to check the wheels and tires for
damage. Hidden tire damage could also be
causing the unusual handling characteristics.
If you find no signs of damage, have the tires
